Hi All,

I hope you are well.

I was wondering if using the `FromSolidDef` method when developing zero-touch nodes in C# is possible. I have tried without much luck. My goal is to draw a few shapes in Revit, store them as strings, and then use the `FromSolidDef` method to recreate them. This approach would be much easier than modelling the shapes directly in Dynamo.

Thanks for your help!

I can confirm it’s doable; You may have better luck with other methods though (i.e. SAT / SAB, where you just consume the path to the file in your zero touch node), depending on your geometry type.

Ahh thanks Jacob. I will give this a go.

It posible, just remember is you need to import [library](https://www.fuget.org/packages/DynamoVisualProgramming.ZeroTouchLibrary/2.13.0.3485/lib/net45/ProtoGeometry.dll/Autodesk.DesignScript.Geometry) before use `FromSolidDef`

```auto
using Autodesk.DesignScript.Geometry

```

Hello

Sorry about the delayed response.  
It seems the issue was that the fromSolidDef method can only be called in a static method. I was attempting to use it in an instance.  
Thanks.
